Title: Improvements relating to the cleaning of air compressors of the centrifugal type
Inventor: PENN ALFRED JOHN
IPC: F04D29/70
Filed: 1953-11-10
Abstract: 758,530. Centrifugal compressors; gas turbine plant. NAPIER & SON, Ltd., D. Nov. 2, 1954 [Nov. 10, 1953], No. 31188/53. Classes 110(1) and 110(3) In a compressor of the centrifugal or combined centrifugal and axialflow type, stationary injection nozzles are circumferentially spaced arround the whole periphery of the air inlet passage, and directed somewhat across the direction of air flow through the passage, and cleaning liquid is delivered through the nozzles in the form of a jet or jets during operation of the compressor so as to impinge on and sweep over the surfaces of the impeller and other parts. A centrifugal compressor for supercharging or scavenging an internal combustion engine is driven by an exhaust gasturbine and draws in air through an air cleaner D. The air cleaner has an annular inlet D<SP>2</SP> and an annular outlet D<SP>3</SP>, between which is an annular chamber D<SP>1</SP> substantially filled with air cleaning material. A fibrous lining E is provided within the outlet D<SP>3</SP> and within the passage leading thereto from 'the chamber D<SP>1</SP>, and on both sides of a wall D<SP>5</SP> separating the outlet D<SP>3</SP> from a transfer passage D<SP>4</SP> leading to the inlet eye B' of the compressor. A ring manifold F is attached by lugs F<SP>2</SP> and bolts F<SP>1</SP> to the wall D<SP>5</SP> and has a series of nozzle openings (not shown) which are inclined about 30 degrees to the axis of the rotor shaft. A cleaning liquid which may be a light oil, such as white spirit, with or without a small proportion of a liquid detergent, is delivered under pressure, as from a pressurized reservoir, through a tube F<SP>4</SP> to the manifold F and injected through the nozzle opening into the compressor while the latter is working under full load. The cleaning liquid passes from the compressor to the cylinders of the internal combustion engine, where it is burnt, the foreign matter cleaned from the compressor surfaces passing out with the exhaust gases. During the cleaning operation, the engine goven- or automatically cuts down the fuel supply to compensate for the fuel value of the cleaihing liquid. Additional cleaning liquid may be injected directly into the diffuser passages. According to the Provisional Specification, the air cleaner may be combined with or replaced by a filter.

Title: A separating device particularly for freeing petrol from water
IPC: C10G33/06
Filed: 1923-12-17
Abstract: 232,287. Zwicky, J. Dec. 17, 1923. Separators.-Apparatus for removing water from petrol, and applicable as a steam-separator, comprises a narrow channel through which the fluid is drawn at relatively high velocity and directed into a chamber where it moves in a path of relatively large cross-sectional area which changes direction through a large angle. The channel opens at a considerable distance from the floor of the chamber or a shield is provided to protect the separated deposit, so that the lower part of the chamber is free from turbulence. Petrol entering through a pipe 1 is directed downwards by a deflector 12 through a narrow annular passage between the lower edge of the deflector and the pipe 1 into a chamber 3, at the bottom of which the water collects while the petrol rises through a chamber 17 to an outlet at the top. The adjacent surfaces of the deflector and the part 1 are. mutually inclined and an increased flow of petrol will lift the defector against the action of a spring 16 and thus increase the cross-section of the annular passage. The part 1 supports a conical shield 8 and the deflector chamber 17 has its lower end formed as a spigot with a projecting lip 18 which may be perforated to facilitate the upward passage of the petrol. The collection of the water is observed through windows 5, and can be drawn off through an outlet 7. Instead of windows a floatoperated indicator may be provided. In the apparatus shown in Fig. 5 a float 31 is provided in a separate compartment, with a window 30. The float operates a valve 32 to admit air and thus stop the flow of fluid, which is drawn through the apparatus by suction. The float may also operate a visual or audible alarm. A conical guide 24 directs the entering liquid down to the surface of the water and a perforated baffle 23 aids in preventing turbulence. Other similar baffles may be fitted at intervals in the length of the chamber. Cover plates 33, 34 allow of access to the interior, elbow connections 35 being provided for inlet and outlet.

Filed: 1952-12-16
Abstract: 710,850. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 16, 1952, No. 31851/52. Class 38(5) In a distance protective arrangement having, for each phase, a relay j responsive to two voltages proportional to the current and voltage of the protected circuit, the voltage proportional to the circuit current is obtained from a secondary winding d, of a current transformer d having an auxiliary secondary winding d 1  which is magnetically coupled to the first winding and has a total burden homologous to the section of the circuit protected, the arrangement being unresponsive to operation by transient fault conditions. In Fig. 1, the relay j is energized from the secondary winding of a potential transformer e and from the secondary winding d 2 . A resistance g and an inductance f are connected to the winding d, and provided with a resistance h representing the internal resistance of the current transformer and the leads interconnecting d 1 , f and g, a burden for the winding d, having resistance and inductance values proportional to the resistance RF and inductance LF of the protected section, allowing for the ratios of the transformers. Each relay may have a coil l, Fig. 3, energized by the two voltages and in addition a coil k connected through a resistance m and a capacitance n for energization from the secondary winding of the associated potential transformer e. By appropriate selection of the resistance m and capacitance n, the relays may be made to function with either reactance or impedance characteristics. The "critical distance" of the relays may be adjusted by means of variable auto-transformers P. In the three-phase arrangement of Fig. 3, an inductance q and a resistance r, are connected in the residualcurrent circuit of windings d 1  through a variable auto-transformer P 1  to introduce a zero sequence voltage drop equivalent to that in the protected circuit to enable the relays to operate correctly for earth faults as well as phase faults. The speci fication sets out in detail the theoretical considerations underlying the invention.
